size
public int size()Description copied from interface:TLongObjectMap
Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.- Specified by:
size
in interfaceTLongObjectMap<V>
- Returns:
- the number of key-value mappings in this map
-
isEmpty
public boolean isEmpty()Description copied from interface:TLongObjectMap
Returns true if this map contains no key-value mappings.- Specified by:
isEmpty
in interfaceTLongObjectMap<V>
- Returns:
- true if this map contains no key-value mappings
-
containsKey
public boolean containsKey(long key) Description copied from interface:TLongObjectMap
Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that key.equals(k). (There can be at most one such mapping.)- Specified by:
containsKey
in interfaceTLongObjectMap<V>
- Parameters:
key
- key whose presence in this map is to be tested- Returns:
- true if this map contains a mapping for the specified key
-
containsValue
Description copied from interface:TLongObjectMap
Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.- Specified by:
containsValue
in interfaceTLongObjectMap<V>
- Parameters:
value
- value whose presence in this map is to be tested- Returns:
- true if this map maps one or more keys to the specified value
-
get
Description copied from interface:TLongObjectMap
Returns the value to which the specified key is mapped, ornull
if this map contains no mapping for the key.More formally, if this map contains a mapping from a key
k
to a valuev
such that(key==null ? k==null : key.equals(k))
, then this method returnsv
; otherwise it returnsnull
. (There can be at most one such mapping.)If this map permits null values, then a return value of
null
does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key tonull
. ThecontainsKey
operation may be used to distinguish these two cases.- Specified by:
get
in interfaceTLongObjectMap<V>
- Parameters:
key
- the key whose associated value is to be returned- Returns:
- the long value to which the specified key is mapped, or
null
if this map contains no mapping for the key
-
put
Description copied from interface:TLongObjectMap
Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only ifm.containsKey(k)
would return true.)- Specified by:
put
in interfaceTLongObjectMap<V>
- Parameters:
key
- key with which the specified value is to be associatedvalue
- an long value value to be associated with the specified key- Returns:
- the previous value associated with key, or no_entry_value if there was no mapping for key. (A no_entry_value return can also indicate that the map previously associated null with key, if the implementation supports null values.)
- See Also:
-
remove
Description copied from interface:TLongObjectMap
Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such thatkey.equals(k)
, that mapping is removed. (The map can contain at most one such mapping.)Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.
If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.
The map will not contain a mapping for the specified key once the call returns.
- Specified by:
remove
in interfaceTLongObjectMap<V>
- Parameters:
key
- key whose mapping is to be removed from the map- Returns:
- the previous long value associated with key, or null if there was no mapping for key.
-
putAll
Description copied from interface:TLongObjectMap
Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of callingput(k, v)
on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.- Specified by:
putAll
in interfaceTLongObjectMap<V>
- Parameters:
map
- mappings to be stored in this map
-
putAll
Description copied from interface:TLongObjectMap
Put all the entries from the given map into this map.- Specified by:
putAll
in interfaceTLongObjectMap<V>
- Parameters:
map
- The map from which entries will be obtained to put into this map.
-
clear
public void clear()Description copied from interface:TLongObjectMap
Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.- Specified by:
clear
in interfaceTLongObjectMap<V>
-
keySet
Description copied from interface:TLongObjectMap
Returns aTLongSet
view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.- Specified by:
keySet
in interfaceTLongObjectMap<V>
- Returns:
- a set view of the keys contained in this map
-
keys
public long[] keys()Description copied from interface:TLongObjectMap
Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.- Specified by:
keys
in interfaceTLongObjectMap<V>
- Returns:
- a copy of the keys of the map as an array.
-
keys
public long[] keys(long[] array) Description copied from interface:TLongObjectMap
Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.- Specified by:
keys
in interfaceTLongObjectMap<V>
- Parameters:
array
- the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.- Returns:
- the keys of the map as an array.
-
valueCollection
Description copied from interface:TLongObjectMap
Returns aCollection
view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.- Specified by:
valueCollection
in interfaceTLongObjectMap<V>
- Returns:
- a collection view of the values contained in this map
-
values
Description copied from interface:TLongObjectMap
Returns the values of the map as an Object array. Note that the array returned is typed as an Object[] and may not be cast to a more specific type. SeeTLongObjectMap.values(Object[])
for a version which allows specifically typed arrays. Changes to the array of values will not be reflected in the map nor vice-versa.- Specified by:
values
in interfaceTLongObjectMap<V>
- Returns:
- the values of the map as an array of long values.
-
values
Description copied from interface:TLongObjectMap
Returns the values of the map using an existing array. Changes to the array of values will not be reflected in the map nor vice-versa.- Specified by:
values
in interfaceTLongObjectMap<V>
- Parameters:
array
- the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.- Returns:
- the values of the map as an array of long values.

Returns a TLongObjectIterator with access to this map's keys and values.- Specified by:
iterator
in interfaceTLongObjectMap<V>
- Returns:
- a TLongObjectIterator with access to this map's keys and values.
-
getNoEntryKey
public long getNoEntryKey()Description copied from interface:TLongObjectMap
Returns the value that represents null in theTLongObjectMap.keySet()
. The default value is generally zero, but can be configured during construction of the collection.- Specified by:
getNoEntryKey
in interfaceTLongObjectMap<V>
- Returns:
- the value that represents a null value in this collection.
-
putIfAbsent

procedure
- aTObjectProcedure
value- Returns:
- false if the loop over the keys terminated because the procedure returned false for some key.
-
forEachValue
Description copied from interface:TLongObjectMap
Executes procedure for each value in the map.- Specified by:
forEachValue
in interfaceTLongObjectMap<V>
- Parameters:
procedure

transformValues
in interfaceTLongObjectMap<V>
- Parameters:
function
- aTObjectFunction
value
-
retainEntries
Description copied from interface:TLongObjectMap
Retains only those entries in the map for which the procedure returns a true value.- Specified by:
retainEntries
in interfaceTLongObjectMap<V>
- Parameters:
procedure
- determines which entries to keep- Returns:
- true if the map was modified.
-
equals
Description copied from interface:TLongObjectMap
Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.- Specified by:
equals
in interfaceTLongObjectMap<V>

equals
in classObject
- Parameters:
o
- object to be compared for equality with this map- Returns:
- true if the specified object is equal to this map
-
hashCode
public int hashCode()Description copied from interface:TLongObjectMap
Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract ofObject.hashCode()
.- Specified by:
hashCode
in interfaceTLongObjectMap<V>
- Overrides:
hashCode
in classObject
- Returns:
- the hash code value for this map
